When you have stitched the wig cap around the perimeter braid, you’ll finish the’loop’ by sewing around the outside of your part. Starting from your last knot on the perimeter braid, skip until another row of braids in your head. Repeat the knot-tying process, then go up to the next row. By the time you’ve sewn around the area, you ought to have a large’U’ shape of knots. Make sure each knot is 1-inch from the center part. Finish off by tying two knots at the base of your sewing, where you began on the perimeter braid.
